Anyone who's ever watched "The Muppet Show" or "Rocky and Bullwinkle" should be able to understand the importance (and challenges) of creating something for both kids and adults. It's a difficult task that can alienate one or both if handled improperly, so I had some reservations when starting Roklienz: On Tour for the first time. However, aside from a few minor missteps it straddles that line quite well.

The Roklienz are rockin' aliens (hah, get it?) looking to dominate their home planets with some sweet tunes. Yup, that's right, Roklienz: On Tour is a music game. Not just any music game, but a sort of iPad adaptation of Elite Beat Agents (or Osu! Tatakae! Ouendan for purists). For those unfamiliar with this particular style of music interaction it essentially boils down to following the on-screen prompts. Players have to tap/swipe/spin/etc the right icons in the proper order and in-time with the music in order to keep the crowd happy and complete each level. The better they do the more coins they earn to put towards unlocking and buying new planets, extras, or power-ups.

Roklienz: On Tour's gameplay isn't groundbreaking at this point, but it's still quite excellent. Following all the various prompts in the proper order can become a real challenge in later levels and it all blends together with the music really well. I've yet to need to resort to using any of the power-ups but I can certainly appreciate their presence. Plus I imagine they're more for the kids. And speaking of, I have to say I'm a big fan of the sketchy/scribbly art style. It's simple and there aren't more than a handful of frames for each animation, but there's a distinct personality shining through all those colorful critters.

I noticed a few technical issues with Roklienz: On Tour, such as a couple of crashes and prompts that don't always feel like they're timed quite right, but my biggest problem is with the pacing and difficulty. The difficulty, in short, is ridiculously easy throughout the entire first planet. I'm sure it's mostly due to wanting to give young iPad players a chance at having fun, and I can totally appreciate that, but it drags on a little too long and feed in to the pacing problem. The pacing problem being that in order to progress I have to play through every song four times in a row, with the difficulty going up a little each time. It starts to become a drag after the third consecutive time.

While I would have preferred having a way to "fast-forward" to the more difficult stuff, I still had fun with Roklienz: On Tour. It's silly and doesn't take itself too seriously, yet provides a lot of unlockable content and challenges for those willing to stick it out through the first third.
